The future of space missions and extended human presence in space requires the ability to provide proper dietary intake for space travelers with minimal resupply from the Earth, as food and food packaging currently represent a significant burden on space mission consumables (Perchonok et al, 2012)
The consumption of carotenoids through whole-food-based diet is a recommendable protective measure since the human body is unable to produce any of the major photoprotective carotenoids considered essential for human vision: β-carotene as precursor of retinal constituent vitamin A, and zeaxanthin and lutein for protecting the eyes by absorbing excess light intensity (Cohu et al, 2014)
Summary
The future of space missions and extended human presence in space requires the ability to provide proper dietary intake for space travelers with minimal resupply from the Earth, as food and food packaging currently represent a significant burden on space mission consumables (Perchonok et al, 2012) This is critical for sustaining an optimal nutritional status for space travelers and for mitigating stress effects from long-duration space travel, including weight loss, hematological changes, and space radiation-induced oxidative cytotoxic stress, protein oxidation, increased muscle proteolysis, impairment of eye health and changes in the central nervous system (Kennedy et al, 2007; Vergari et al, 2010; Cohu et al, 2014). It is critical to incorporate in SLSSs plant-based fresh functional food production to support human presence during long-distance space travel or extra-planetary habitation
